Invaders: Predicting Risks from Invasive Species Before It Happens (Jul
11, 2012)ScienceDaily; The Norwegian University of Science
and Technology.
A coalition of researchers from the Norwegian University of Science and Technology
(NTNU) and staff from the Norwegian Biodiversity Information Centre have created
a unique quantitative method that enables researchers and others to assess the
environmental risks posed by non-native species. While the method is tailored
to the Norwegian environment, it can easily be adapted to other countries, and
fills a vital need internationally for a quantifiable, uniform approach to classifying
and assessing alien species, the developers say. This approach may help determine
how dangerous an introduced species will be in its new environment before the
damage takes place.
